Area of Science:

  • Materials Science
  • Biotechnology
  • Chemical Engineering

Background:

  • Existing hydrogel microparticle (HMP) synthesis methods lack efficient approaches for creating functional hybrid protein-polymer HMPs.
  • Emulsification through porous media is a promising technique for microparticle fabrication but has not been applied to hybrid protein-polymer systems.

Purpose of the Study:

  • To introduce and validate the aided porous medium emulsification for hydrogel microparticle synthesis (APME-HMS) system.
  • To demonstrate the system's capability in synthesizing functional hybrid protein-polymer HMPs while preserving protein integrity.
  • To explore the potential applications of these novel HMPs.

Main Methods:

  • The APME-HMS system utilizes a 3D porous structure to emulsify immiscible phases for HMP production.
  • Responsive bovine serum albumin (BSA) and polyethylene glycol diacrylate (PEGDA) HMPs were synthesized using the APME-HMS system.
  • Cytochrome c (cyt c)-PEGDA HMPs were fabricated to demonstrate biosensing capabilities for hydrogen peroxide (H2O2) detection.

Main Results:

  • The APME-HMS system successfully synthesized HMPs of various sizes with tunable properties.
  • Protein structural integrity and functionality were maintained during the synthesis process.
  • The system demonstrated efficient HMP synthesis using low protein volumes (≈50 µL) and concentrations (100 µm) within minutes.

Conclusions:

  • The APME-HMS system offers a cost-effective, biocompatible, and scalable method for producing diverse functional protein-polymer HMPs.
  • This technique preserves protein functionality, enabling applications in biosensing (e.g., H2O2 detection).
  • The APME-HMS system holds potential for controlled drug delivery, 3D bioprinting, and other biomedical and culinary applications.
